The Lowdown
Right, listen up. Rusty here. Let’s talk about Jaconé for the next couple of weeks.
The first few days are pretty flat and ordinary, but there’s a real pulse of size and energy coming through mid-month. Most of the run is small to moderate, but that second week is where the meat is. Water temp is sitting at 73°, which feels about average for this time of year—nothing wild there.
We start off on Sunday the 2nd with a tiny 3 ft ESE windswell, cross-off breeze, real poor stuff – not worth a paddle. Monday the 3rd is better: that morning you get 4 ft from the ENE with a clean 3 mph offshore from the NE. It’s surfable but very ordinary. By Monday afternoon the wind shifts cross-off again but the energy is moderate (202). Tuesday the 4th morning has offshore wind and 3 ft but the period jumps to 8 seconds. Still ordinary.
Wednesday the 5th morning though—that’s the first real standout early on. We’ve got a 3 ft swell from the south with a long 12-second period, light offshore wind from the NNE, and the combined energy is pumping at 615. It says expect very good surf conditions. That’s clean, lined-up, proper. Get on it.
Thursday the 6th morning has 5 ft from the ENE, offshore breeze, decent energy (341) – good, solid, but not a standout like Wednesday. Friday and Saturday drop right off.
Sunday the 9th afternoon brings a glassy 4 ft from the ENE, energy at 235, wind is glass – that’s a nice, clean little session for a mellow surf. Totally ridable.
Now, the big stuff. Monday the 11th is where it changes. The morning sees 7 ft from the SSW, cross-off wind, and a massive 1067 energy reading. That’s borderline big. Afternoon pushes 8 ft and 1379 energy – this is getting heavy. Tuesday the 12th morning hits 10 ft from SSW with a 13-second period and energy of 3098. That’s a beast. But the comments say it’s too big for the break – unless you’re an expert, stay out. The wind is light cross-shore, which is good for shape, but with that size at a beach break, it’s gonna be a washing machine for most. Wednesday the 13th and Thursday the 14th hold at 7 to 8 ft, long period, cross-off winds – that’s expert territory, but clean. By Friday the 15th and Saturday the 16th we drop back to 7 to 7 ft from the south, solid offshore winds, still plenty of energy. Decent for experienced surfers.
After that, Sunday the 17th fades to 5 ft and then 2 ft by Monday the 18th. The last few days are ordinary again.
Best on offer: Wednesday the 5th morning – that 3 ft S groundswell, light offshore, clean, and good energy is the pick for a fun, quality session without the insanity. If you’re an expert and hungry for power, Tuesday the 12th morning has the biggest, cleanest swell of the run but it’s for big-wave crew only.
Keep your eye on the forecasts for that second week – the long-range stuff looks promising but less certain.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
